I wrote my on help system (based on the now defunct UniHelp). Worked fine but I kept getting errors after upgrading to Xojo 2020V1. It seems the HTML title viewer TitleChanged event is no longer passing the page title in the newTitle parameter.
From the parent app I can request a help page. Works fine. On the help view window I have controls to step up or down the table of contents. That seems to work as well, it’s when I go back to the parent app and request help again it fails. So far as I can make out its the navigating up and down the TOC that is causing the problem.
The live version of the app was compiled with Xojo 2019R2 and it works properly. However if I compile the source for that version it also fails.
Anyone got any ideas? This is a Mac app.
